      節能型側開式鑄鐵拍門是保證泵站安全運行的重要設備,在泵站中其作用是斷流和防止停機時水倒流,主要用于:防洪排澇、農田灌溉、城市給排水和跨流域調水,以及各大型工礦企業的供水和配水等。

      節能型側開式鑄鐵拍門由門板、門鉸、門座和密封件等組成。門板通過門鉸安裝在門座上,根據國內泵站的應用情況,鑄鐵拍門的門形圓形和矩形兩種。一般出水管口徑小于、等于2m的(即口徑1.6的泵)用圓形鑄鐵拍門,大于該口徑的用矩形鑄鐵拍門。


      節能拍門主要技術特點


      1、無需任何啟閉裝置,能自動關閉。節能型側開式鑄鐵拍門與懸掛式鑄鐵拍門相比最顯著的特點是:將閥體鉸軸豎向布置,并設計了一個最佳傾斜角度,利用門重分力作閉門的動力,不管大、中、小通徑鑄鐵拍門,均無需任何啟閉裝置。

      2、 安 全穩定,節能高效。節能型側開式鑄鐵拍門運行時阻力小,開啟角度大,閉門時撞擊力小,消除了水錘和出水時產生的漩渦;無需、手、電、氣、液控制,不要人工 操作,節省大量人力物力,提高泵站運行可靠性和裝置效率,降低運行維護成本,降低泵站耗能。

      Energy-saving side-open cast iron circular clapper door is an important equipment to ensure the safe operation of pumping stations. Its role in pumping stations is to cut off the flow and prevent water backflow during shutdown. It is mainly used for flood control and drainage, farmland irrigation, urban water supply and drainage and inter-basin water transfer, as well as water supply and distribution of large-scale industrial and mining enterprises. The energy-saving side open cast iron flap gate is composed of door panels, door hinge, door seat and seals. The door plate is mounted on the door base through the door hinges. According to the application of domestic pumping stations, there are two kinds of gate-shaped circular and rectangular iron flap doors. Generally, the outlet pipe diameter is less than or equal to 2m (that is, the diameter of 1.6 pump) with round cast iron clap door, larger than the diameter of the rectangular cast iron clap door. The main technical features of the energy-saving door are 1, no need for any hoist device, and it can be automatically closed. The most remarkable feature of the energy-saving side-open cast iron flap door is that the hinge shaft of the valve body is arranged vertically and an optimum angle of inclination is designed. The power of the door is used to close the door, and no opening or closing device is needed for large, medium or small diameter cast iron flap door. 2, safety and stability, energy saving and high efficiency. The energy-saving side-open cast iron flap door has the advantages of small resistance, large opening angle, small impact force when closing the door, eliminating the whirlpool produced by water hammer and water discharge, no need for manual operation, saving a lot of manpower and material resources, improving the operation reliability and equipment efficiency of pumping station, reducing the operation and maintenance costs. Reduce energy consumption of pumping stations.
